Ways to temporarily gain Diehard-like ability?

[PapaZorro]

Hi there, I was just wondering if there were any magic or alchemical items that allow you to still act while you're at negative hit points? They can be consumable or whatever, just hoping there's something out there that can do this.

shape shift into something that has ferocity.

Monstrous Physique III, Beast Shape III; Battle Trance (from ARG) is within potion range.

Not the same as allowing an action while dying, but can anyone in your party cast stabilize?

Does your GM use Hero Points? That might be another avenue.
